I have recently purchased this silver cup/beaker (see below) which is still in transit. I am interested if anyone can offer an opinion if this piece appears to be genuine based on style, construction, marks, etc.
I found another cup that was offered at a German auction house with similar marks which they had attributed to Johann Jebenz (also pictured below).
Perhaps one unusual feature of my cup is that it appears to have a possible French bigorne mark underneath the rim of the foot?
Any information/feedback would be appreciated.
